#4261158 How to repair a CX-75 LightPen?

Posted by luckybuck on Fri Apr 19, 2019 12:23 PM

:-) Yes. :-)


But first, we will publish on how to r/w with 6,000 baud on and from a cassette recorder... Breakthrough was made again at the NOMAM meeting last week. Meaning transfer rates more than 10 times as in the golden age...

Thanks Doctor, we tested with an Atari 130 XE in port 2. Sadly, with the same results. Further, we have used crt TV. Will try another approach at the next meeting. BTW, port 4 of the Atari 400 should work, if I have understood correctly.

@BigO: $24.2 plus customs plus tax for overseas... will result in something like > $30... But the price is not the problem, but they why, especially for others. For the computers we have:

Technical Reference Notes or Manuals, else Hardware Manual. But not for the light pen. :-( Would love to add this for the Wiki.

Uh ha, didn't knew, that LJK was in Saint Louis, Missouri! When I got my cart in the 80's (without a manual, of course), they told me, it was from the UK! Glad, this could be corrected. Thank you so much bcombee! So, after 38 years, we are able to close this case. May I upload the manual to the Wiki, too? Of course, with credits to LJK and you. :-)

Yes, very true, RAMBO is a fiction figure, which is not real, but Allan is the real deal!


He has done APX:

https://atariwiki.or... (APX) Software

nearly on his own, just for us!


=> we can't thank Allan enough.


All other are free to help him...


There are 3 major projects still:


https://atariwiki.or...System Software


is one of them...

Posted by luckybuck on Sun Mar 17, 2019 1:23 PM

Sadly not. All we have is here:

https://atariwiki.or...?page=Edit 6502

Edit 6502 was an incredible fast assembler! What James Bond as export product for movies, Edit 6502 was for Atari Assemblers.

Either  bcombee finds it or our friends in the UK/GB.

Otherwise it is lost in time, like tears in rain, which is really a great loss!

Edit 6502 never got the fame, it deserves.

Harry, my deepest respect for your work! I really appreciate very much.


Please don't misunderstand, if I join Allan here. Besides this, it is a good idea to centralize everything, not just the scans. There is still a bunch of work to do so...


Allan and others have scanned so much already, so you may do double work, but we need your excellent work for the big remaining stuff. :-)


If games are concerned, Atarimania and archive.org are best search addresses. For the edu and serious stuff, again archive.org and AtariWiki. Please see the links in my signature.


Beside this, be sure, we will help you in any way possible. Don't hesitate to ask us.


3-4 minutes is a lot for just one page. Modern scanners in a copy shop do the job with best resolution (600 dpi) in less than 10 seconds. I don't know your budget or money you can spend on this, but this would save you a lot of time. Maybe we find a way for crowd founding?


Thank you so much für your work and for sharing. :-)

You can contact our hero Steve here:


You and he belong to the Unreplaceables! And I didn't use these ' symbols...


If you have problems, let me know, will contact Steve and send you a pm.

Alfred, we are glad, to have even this! Feel free to get the original one. Btw, you know, that the SynAssembler is adapted from the S-C Assembler II Vers. 4.0?



Anyway, have exported all the MAC/65 source files into TXT files, please see attachment. Major parts are documented, so you just have to hybridize the code with the comments from the S-C Assembler II...


We would be glad to see...


Else, why don't ask Steve himself? Else 2 on github?



Please understand, that the IMF team has no intention to retire, but 3 major projects have to be finished:


a) Pascal (Artari version, Kyan, CNSL etc.) in the way ACTION! already is




c) finishing this: https://atariwiki.or...System Software


Years or work before us...

#4232260 6502 & 6510 Mug big & small :-)

Posted by luckybuck on Mon Mar 4, 2019 8:51 PM

Hi together,


There were some misunderstandings, therefore, I hope I can clear this with this post.

Bruce and Laura sell a 6502 (red color)- and a 6510 (blue color)-command mug in big (15 oz) and small (11 oz, also called the nibble edition). The order is always(!) in the US via their website:
but shipping is different!
If you order for example from the EU, then shipping is from within the EU! => much cheaper.
Exchange rate from $ to € as of 3/4/19: 1 : 0,88
Further, 1 US-oz = 29,5735295625 EU-ml.
This results into the following matrix (no matter if 6502 or 6510):

11 oz = 325,3 ml for $17,95 else 15,83 € for the little mug
15 oz = 443,6 ml for $21,95 else 19,36 € for the big mug
Plus shipping:
- Economy (5-10 business days after order) for $4,63 = 4,08 €
- Flat Rate (5-10 business days after order) for $6,45 = 5,69 €
- Standard (3-5 business days after order) for $24,31 = 21,44 €
So, I hope, the fans from the EU have a clearer picture.
Still missing, the coast to coast version mug with 6502, 6510, 65816 and so on in Atari rainbow colors depending on the heat of the coffee or tea... ;-)

#4228907 Atari CX4xy list-who can help to fill up it up?

Posted by luckybuck on Wed Feb 27, 2019 3:02 PM

Hi together,


One spin-off out of the Atari Accountant is a new list for the Atari CX4xy boxes.


Where x and y can be a number from 0 to 9, please see below for the actual list.


Interesting is the fact, we had 404 for the 810 drive and the same(!) program obviously for the 815 drive, the 'beast', under the mark: 408...


While the A800 with 48 KiB remains the same...


So, does anyone know about the lables not yet described, e. g. 407, 409 and so on?


Would be of great help to complete this part of Atari history.


Thank you very much in advance. :-)

@bfollowell: yes, Nezgar is right, please read my article. I doubt, 815 were sold. Accoding to Curt Vendel, there are just 75 on the whole planet, not more. As Nezgar told, the 815 is DD only(!), that is important! You can't read or write SD disks! So, who should buy something like that? You have to buy an 810, too. Why Atari made this? As a scientist, I don't like to suggest, I prefer to know. But here, it is difficult, because the people in charge deny to be interviewed. Therefore, I just can guess, that the research & development department tried to gain new markets and new customers. We have to consider, when this had beeen done the right way, we now would speak of HCs, instead of PCs...


@slx: Thank you very much! That is a big faux pas of mine! Already corrected in the Wiki. Thanks. :-)

Well, 5:50 am maybe too late for me, you are right, we can clear the blank ones. So, the CX8202 is remaining. Thank you! :-)

Don't put your light under the table! You were of great help!

The problem with the destroyed sector in DD took us a year to come by!

All the programs available support the 'normal' drive, not the 'beast'...

This alone decelerated the project very much. Especially without having access to the 75 drives worldwide available...


Yes, this is my special part, the time from 1979 up to 1982... The beginning so far... many still shrouded in mystery. :-(

Text Editor v1.0A went to 1.0C, you know? -> Wiki


Big sorry, I just added the DOS 2.0D from my archive. This is not delivered with the CX401 as a standalone disk. We still search for a Kryo image of this and(!) the CX8202, because these disks boot faster than normal!
